Axle back is a great investment if you can get it cheap enough which is why it is a smart decision to buy my Works AB for $100......Plus if you ever want to eventualy upgrade (like I did) then there will always be someone that will be willing to purchase it at 1/3 of retail as long as you keep it in good condidtion. Or the Works upgrades will bolt right up but it was just a little to rich for me although they make great quality pieces!
